A primary object of the invention consists in including two horizontalcylindrical pins the front tapering ends of which are adapted to slidefreely within the upper part of the hinged barrel section of the gun soas to operatively engage cooperating recesses formed in the barrelledsection of the gun. A connecting plate coupled with said pins istransiently shiftable under the action of an eccentric projectioncarried by a rotary ring the upper surface of which is provided with atenon through which said ring is driven directly into rotation throughthe head of a controlling toggle lever.

A screw extending axially of the ring defines the vertical location ofthe assembly of the ring and connecting plate with reference'to thecontrolling toggle while a cylindrical section of said screw allows saidplate to slide freely longitudinally over the ring. A further screwengaging the end of the hinged barrel of the gun forms through itscylindrical head a guide for this longitudinal sliding of the connectingplate.

According to a further object of the invention, the means locking thebarrel-locking means in their inoperative position include aspring-urged pin slidably carried by the head of the toggle within anoblique bore and adapted upon setting of the toggle in itsbarrel-releasing position and consequent release of the barrel-lockingpins, to engage and push a movable rod the front projecting end of whichfacing the rear surface of the barrelled section of the gun is pushedback by said section of the gun when the latter is closed, whereby saidmovable rod returns the slidable pin within the head of the toggle whichmay thus be shifted back into its operating barrel-locking positron.

According to a still further object of the invention, the double-actingtriggering system includes two triggers cooperating with sears andadapted to be operated independently of each other for firingrespectively through the lower and upper barrels. Now, the upper end ofthe right-hand trigger carries a pivoting mass or weight the inertia ofwhich provides, after the firing of the first shot, the interengagementof said trigger with a notch provided in the sear of the left-handtrigger whereby it becomes possible for said first-mentioned right-handtrigger to fire the second shot and to behave thus as a singlenonselective trigger providing for the firing of the two shots throughthe two barrels in the desired sequence.

These objects will be disclosed inter alia with further detail in thefollowing description of an embodiment of my invention given out by wayof a mere exemplification. In the accompanying drawings illustratingsaid embodiment:

FIG. 13 is a partly sectional plan view extending through line g-h ofFIG. 12 after removal of the hammers.

The sporting gun provided with superposed barrels and incorporating anembodiment of my invention includes chiefly a hinged barrel section 1 inthe upper part of which may slide longitudinally two cylindrical pins 2the front ends 2 of which are slightly frustoconical and engage, whenthe gun is to be locked in its closed position, the correspondinghousings 3 in the barrelled section 3 of the gun. Said pins are providedat points facing each other with notches 2 for engagement by cooperatingtenons 4 formed on a connecting plate 4 extending in the horizontalplane passing through the axes of the pins and assuming a translationalmovement through the agency of a ring 5 revolving freely within a recessin the hinged barrel I.

Said ring 5 carries on its lower surface resting on the plate 4 aneccentric tenon 5 (FIG. 2) engaging a slot 4 formed in the plate 4, saidslot being perpendicular to the longitudinai axis of the pins 2 whilethe upper surface of said ring 5 carries a tenon 5 fitted within acorresponding groove formed in the lower surface of the head 6 of thecontrolling toggle lever 6. An assembling screw 7 passes in successionthrough the connecting plate 4 and ring 5 and its end is screwed intothe head 6' of the control toggle. Said screw 7 shows furthermore acylindrical bearing surface 7 which provides for the free guiding of theelongated longitudinal slot 4 formed in the plate 4, while the head ofsaid screw holds the latter at a constant height. To improve thelongitudinal guiding of the axially shiftable plate 4 a screw 8 engagesthrough its cylindrical head 8 a longitudinal slot 4 in the plate inorder to cut out any risk of wedging of the pins 2 in their recesses.

By reason of these arrangements it is apparent that the angular shiftingof the control toggle 6 produces through the eccentric tenon 5' arearward sliding of the connecting plate 4 and consequently of the pins2 which unlock the barrel which is thus released as illustrated in FIG.3.

It should be remarked that the head 6 of the control toggle 6 isprovided along its rear outline with a recess 6 the sloping surface ofwhich is engaged by a stud 9 slidingly housed within a blind bore formedwithin the upper part of the barrel 1, said stud being subjected to thepressure of a coil spring 10 which urges said stud towards the toggle soas to allow the return of the latter into its operative position forwhich the barrel is secured to the barrelled section of the gun by thepins 2.

A pin 11 housed in a blind bore formed obliquely in the front surface ofthe head 6 of the toggle 6 is urged outwardly of the latter by a coilspring 12 (FIG. 6) so as to engage, at the end of the releasing strokeof the toggle, the rear end of a cooperating pusher rod 13 slidinglycarried by the barrel. Said pusher rod 13 is thus urged forwardly by thepin 11 then in registry with it and entering the rear end of the borehousing said rod 13.

The barrel being released, the toggle 6 is thus locked in position bythe interengaging pin 11 and rod 13. When closing the gun I the rearsurface of the barrelled section 3 engages the front projecting end ofthe pusher rod 13 so as to make the latter move rearwardly and push backthe pin 11 against the pressure of the cooperating coil spring 12. Thetoggle is thus released in its turn and returns into its barrel lockingposition into which it is urged by the stud 9 acting on the slopingsurface of the notch 6 The double-acting triggering system includes twotriggers 14 and 15 adapted to be operated separately as usual, for theseparate firing through the upper and lower barrels. Additionally theright-hand trigger 15 carries at its upper end a small weight 16pivotally secured to said trigger, said weight providing for thecoupling, after the first shot is fired, between said right-hand triggerand the left-hand sear 17 (FIG. 12) so as to allow a subsequent firingthrough both barrels upon operation of said trigger 15.

To this end, the right-hand trigger 15 which normally controls thefiring through the lower barrel is pivotally secured to the spindle 18passing through the trigger guard 19 whereas the right-hand sear 20,also pivotally secured to said spindle 18 adjacent the trigger 15,terminates at its rear end with a nose 20' engaging permanently theinner end 15 of the trigger 15 through the agency of a hairpin-shapedspring 21.

At its front end, the right-hand sear terminates with a nose 20 whichcooperates after the cocking operation with a notch in the right-handhammer 22 providing for the firing through the lower barrel, said hammerbeing pivotally secured to the spindle 23 extending through the triggerguard.

The hairpin-shaped spring 21 includes a forwardly projecting extensionclamped within a sloping slot formed in the corresponding upstandingflange of the trigger guard 19 while the central round portion 21 of thespring 21 engages an arcuate recess 19 in the trigger guard. The rearbent extension 21 of the spring 21 engages a bore 20 in the sear 20 soas to urge the nose 20 of the latter against the inner end 15 of thetrigger 15. I

The right-hand trigger 15 may engage through its rear end the strapshaped end 16 of the weight 16 pivotally secured to said trigger throughthe agency of the spindle 24 passing through said strap 16.

Said weight 16 includes a shaped transversely shifted extension thefront surface of which forms a bearing 16 cooperating with the shapedsurface 22 of the right-hand hammer 22 (FIG. 12).

Said weight 16 is furthermore urged forwardly at all moments against theupper surface of the trigger 15 by a torsion spring 25 surrounding thespindle 24 as clearly shown in FIG.

It should be remarked that the weight 16 is provided in registry withits strap-shaped section with an upper notch 16 extending transverselybeyond the shaped extension of the weight so as to mate with the lowershaped notch 17' formed in an extension rising above the left-hand sear17.

Said left-hand sear l7 lies adjacent the left-hand trigger l4 and ispivotally secured together with the latter to the spindle 18.

The left-hand sear 17 is provided at its rear end with a nose l7permanently urged against the cooperating bent end 14 of the left-handtrigger 14 by a hairpin-shaped spring 26 which is similar to the spring21 and arranged symmetrically of the latter.

The front end of the left-hand sear forms a nose 17 adapted to engage,after the cocking operating, a notch in the left-hand hammer 27providing for the firing through the upper barrel (FIG. 12).

Each of the triggers l and 14 forms at its rear end a flat sectiondesignated respectively by and 14 both of said flat sections cooperatingwith the end of the safety lever 28.

The double-acting triggering system described hereinabove operates asfollows:

Upon cocking of the hammers the right-hand hammer 22 pivots and actsthrough its shaped surface 22 on the bearing surface 16 of the weight 16and constrains it to rock rearwardly around its spindle 24 against thepressure of the spring 25 as illustrated by the arrow F (FIG. 12). Atthe end of the cocking operation the upper notch 16 formed in saidweight registers with the rear of the notch 17 in the left-hand sear 17.

When the right-hand trigger 15 is depressed so as to fire a shot throughthe lower barrel, it carries along with it the nose of the correspondingright-hand sear 20 which pivots round the spindle 18 and releasesconsequently the right-hand hammer 22.

At the same moment, the weight 16 is released and the coil spring 25makes it pivot forwardly so that its notched section 16 is shifted intothe notch 17 formed within the raised extension of the left-hand sear17.

When the shot is fired, the weight 16 is projected rearwardly under theaction of its own inertia as a consequence of the reaction produced bythe marksman s shoulder and this prevents the untimely firing of thesecond shot by an unintentional pressure of the marksman s finger on theright-hand trigger at the moment of the kick of the gun.

After the first shot has been fired, the weight 16 is returned forwardlyby its spring 25 for a final engagement of its notched section 16underneath the nose overlying the notch 17 in the raised extension ofthe sear 17 which is thus coupled in a vertical direction with theright-hand trigger 15.

Obviously the firing of the second shot may be performed as well bydepressing the left-hand trigger in a conventional manner.
